6 sweets cost 24p altogether how much do 5 sweets cost
To calculate the cost of 5 sweets when 6 sweets cost 24p, divide the total cost by the number of sweets to determine the cost of one sweet, then multiply by 5. The cost for 5 sweets is 20p.
To find out how much 5 sweets cost when 6 sweets cost 24p altogether, we first need to calculate the cost of one sweet. We divide the total cost by the number of sweets to get the cost per sweet. Here's how it's done:
Find the cost of one sweet by dividing the total cost of 6 sweets (24p) by 6: Cost per sweet = 24p / 6 = 4p.Now, multiply the cost per sweet by the number of sweets you want to find the cost for, which in this case is 5: Cost for 5 sweets = 4p / sweet × 5 sweets = 20p.Therefore, 5 sweets would cost 20p.

Leslie can determine which option will give her more yogurt by comparing the weights of the two options.
Explanation:To determine which option will give Leslie more yogurt, she needs to compare the weights of the two options. First, she needs to convert the weight of the first option from pounds to ounces. Since 1 pound is equal to 16 ounces, the 2 pound container is equal to 32 ounces. Next, she can compare the weights of the two options. The first option is 32 ounces and the second option is 5 containers of 6 ounces each, which is a total of 30 ounces. Therefore, the first option will give Leslie more yogurt.

Scores on a statewide standardized test are normally distributed with a mean of 12.89 and a standard deviation of 1.95. Certificates are given to students whose scores are in the top 2% of those who took the test. This means that they scored better than 98% of the other test takers. Marcus received his score of 13.7 on the exam and is wondering why he didn’t receive a certificate. Show all work to determine whether Marcus’ score was high enough to earn a certificate. Write a letter to Marcus explaining whether or not he will be receiving a certificate. Include a brief summary of your statistical analysis in your letter.

Answer:
I believe the answer is (C.2)
Step-by-step explanation:
The answer isn’t 1. I took the test and ‘B’ is incorrect
Final answer:
C: 2
To find the average rate of change of the function f(x) from x = 0 to x = 1, we compute (f(1) - f(0)) / (1 - 0), which results in (3 - 1) / 1 = 2. The average rate of change is therefore 2.
Explanation:
To calculate the average rate of change for the function f(x) = −x⁴ + 4x³ − 2x² + x + 1 from x = 0 to x = 1, we use the formula:
Average rate of change = ∆f/∆x = (f(x_2) - f(x_1)) / (x_2 - x_1)
First, we need to find the values of f(x) at x = 0 and x = 1:
f(0) = −(0)⁴ + 4(0)³ − 2(0)² + (0) + 1 = 1f(1) = −(1)⁴ + 4(1)³ − 2(1)² + (1) + 1 = 3Using these values, we calculate the average rate of change:
Average rate of change = (3 - 1) / (1 - 0) = 2 / 1 = 2
Therefore, the average rate of change of the function from x = 0 to x = 1 is 2.
use analytic methods to find the extreme values of f(x)= (1/x) + lnx on the interval 0.5 ≤ x ≤ 4 and where they occur
To solve a three-variable system of equations, you can use a combination of the elimination and substitution mehtods.
True or False ...?
Final answer:
True, a combination of the elimination and substitution methods can solve a three-variable system of equations.
Explanation:
The statement is True. We can use a combination of the elimination and substitution methods to solve a three-variable system of equations. In the elimination method, we aim to eliminate one variable by adding or subtracting the equations, allowing us to solve for the remaining variables. This method works well when the coefficients of one variable are opposites in two equations.
In the substitution method, we solve one equation for one variable and substitute this expression into the other equations. This allows us to solve for the remaining variables. This method is more straightforward when one equation can be easily solved for one variable.
What is 0.98 rounded to the nearest thousandth?
The number 0.98 already has a zero in the thousandths place and no further digits; hence it remains as 0.980 when rounded to the nearest thousandth.
The given number, 0.98, when rounded to the nearest thousandth, does not change because it has a zero in the thousandths place. To round a number to the nearest thousandth, you look at the digit in the ten-thousandths place. If this digit is 5 or greater, you round up.
If it is less than 5, you keep the digit in the thousandths place as it is. Since 0.98 has a zero in the thousandths place already and there are no further digits, it remains as 0.980 when rounded to the nearest thousandth.

Write an equation of the direct variation that includes the point (9, –12).
(A.) y = 1 1/3x (B.) y = - 1/12x (C.) y = 1 1/3x (D.) -3/4x ...?
The equation of direct variation for the point (9, -12) would be y = -1 1/3x. The constant of variation, 'k', is found by dividing 'y' by 'x'. Therefore, 'k' is -12/9, which simplifies to -1 1/3.
Explanation:In a direct variation, the equation can be represented in the form y = kx, where 'k' is the constant of variation. Here, 'k' can be found by dividing 'y' by 'x'. So, in the given point (9, -12), 'k' would be -12/9, which simplifies to -4/3 or -1 1/3. Therefore, the equation of the direct variation that includes the point (9, -12) would be y = -1 1/3x. The provided options don't include this equation, so it might be a mistake in the question options. Remember, the correct equation should always have 'y' and 'x' directly vary, and 'k' have the same sign as the given 'y' value.

What is the sum of square root -2 and squareroot -18
The sum of the square roots of -2 and -18 is [tex]\( 4\sqrt{2}i \)[/tex], where i is the imaginary unit.
The sum of the square roots of -2 and -18 involves complex numbers because both -2 and -18 are negative.
The square root of a negative number is not a real number, but it can be expressed using imaginary units.
The square root of -2 can be represented as [tex]\( \sqrt{-2} = \sqrt{2}i \),[/tex] where i is the imaginary unit, defined as [tex]\( i = \sqrt{-1} \).[/tex]
Similarly, the square root of -18 can be written as [tex]\( \sqrt{-18} = \sqrt{18}i \).[/tex]
Now, to find the sum of these square roots:
[tex]\[ \sqrt{-2} + \sqrt{-18} = \sqrt{2}i + \sqrt{18}i \][/tex]
[tex]\[ = \sqrt{2}i + \sqrt{2 \times 9}i \][/tex]
[tex]\[ = \sqrt{2}i + 3\sqrt{2}i \]\\\\ = (\sqrt{2} + 3\sqrt{2})i \][/tex]
[tex]\[ = 4\sqrt{2}i \][/tex]
So, the sum of[tex]\( \sqrt{-2} \) and \( \sqrt{-18} \)[/tex] is [tex]\( 4\sqrt{2}i \).[/tex]

At a gas station, the price of a regular gas was $3.80 per gallon on monday. the price increased to $3.85 per gallon on tuesday. round the price per gallon for each day to the nearest tenth of a dollar.
Answer:
A round number is less accurate, but easier to use, because you get rid of certain decimals.
There are some rules to do this:
If we want to round a number to the nearest tenth, we have to look what's the unit after it, if that unit is more than 5, we round the tenth to the upper number. For example, 10.66 would be rounded to 10.7.If we want to round a number, and the next digit is lower that 5, we just maintain the same digit. For example, 10.44 would be rounded to 10.4However, there's a specific case, if we want to round a number to the tenth, and the following digit is 5, we could round up or round down the tenth digit. If the digit we want to round is pair, then we maintain the same digit, if it's odd, we can round to the upper digit. For example, 10.65 would be rounded to 10.6, and 10.75 would be rounded to 10.8Therefore, according to these rules, the round number would be $3.8 and $3.8

three randomly selected households are surveyed. the numbers of people in the households are 1,3,8 assume that samples of size n =2 are randomly selelcted with replacement from the population of 1,3,8. Listed below are the nine different sampls
1,1 1,3 1,8 3,1 3,3 3,8 8,1 8,3 8,8

The variances for the samples were calculated, and then the probability of each distinct variance value was found. The results were summarized in a table showing the probability distribution of the variances.
Explanation:The variance of a sample is calculated using the formula:
s^2 = Σ ( xi - X_bar )^2 / (n - 1).
Where 'xi' represents each value in the sample, 'X_bar' is the mean of the sample and 'n' is the number of values in the sample. Let's calculate the variance for each of these samples:
Next, find the probability of each distinct variance value by counting the number of times it occurs and dividing by the total number of samples (9 in this case). The sampling distribution of the variances with probabilities looks something like this:
Variance = 0 : Probability = 3/9 = 0.33Variance = 2 : Probability = 2/9 = 0.22Variance = 25 : Probability = 2/9 = 0.22Variance = 49 : Probability = 2/9 = 0.22Learn more about Variance and Probability here:https://brainly.com/question/31698743
